Just last month, Gadling took you on a journey inside the world of urban exploration, bringing you on a behind-the-scenes look at the urban explorers who are inventing new ways of visiting the areas under, above and inside the cities we traverse every day. Today, we’ve got another intriguing look at the urban exploring phenomenon to share with you, courtesy of the short film series above called “Undercity: Las Vegas.”

Part of an interesting collaboration with shoe company Palladium, the film series follows the exploits of urban historian Steve Duncan, profiled in Gadling’s recent feature, along with director Andrew Wonder, as they investigate the subterranean water tunnels and unfinished construction sites that comprise the lesser-known side of this urban neon mecca of gambling and nightlife. In this particular clip, Duncan manages to sneak inside the as yet unfinished Fontainebleu Resort Las Vegas, climbing nearly 60 floors to take in an eye-popping view of the early Vegas dawn.

Though the trespassing on the construction site is clearly illegal, it’s an intriguing look inside the urban underbelly that few Las Vegas visitors ever see. Those interested in seeing the full film can head over to Palladium’s video hub to check out Part 1 and Part 2 of this ongoing series.
